Viracept

Viracept is an antiretroviral drug used in the treatment of HIV/AIDS. It is a type of drug known as a protease inhibitor, which works by preventing the virus from replicating within the body.

History

Viracept, also known by its generic name nelfinavir, was approved by the FDA in 1997. It was developed by the pharmaceutical company Agouron Pharmaceuticals, which is now a subsidiary of Pfizer.

Mechanism of Action

As a protease inhibitor, Viracept works by binding to the HIV-1 protease, an enzyme that the virus needs to replicate. By inhibiting this enzyme, the drug prevents the virus from creating new copies of itself within the body's cells.

Usage

Viracept is used in combination with other antiretroviral drugs as part of a treatment regimen known as HAART. This approach is designed to reduce the amount of virus in the body to undetectable levels and slow the progression of the disease.

Side Effects

Like all medications, Viracept can cause side effects. The most common include diarrhea, gas, and rash. In rare cases, it can cause more serious side effects such as liver problems or changes in the body's fat distribution.

Resistance

Over time, some strains of HIV can develop resistance to Viracept. This is why it is important to take the medication exactly as prescribed and to regularly monitor the amount of virus in the body.
